AcREAM-nAislNe APPARATUS.

SPECIFICATION forming part of Letters Patent No. 348,540, dated August 31, 1886.

Application filed May 25. 1886.

To all whom/it may concern,.-

Beit known that we, FREDRICK W. Mosa- LEY andl J onN G. Parral-IARD, the former having legal residence at Poultney, Rutland 5 county, State of Vermont, but doing business at Clinton, Clinton county, State of Iowa, and the latter residing at Clinton, Clinton county, State of Iowa, have invented certain new and useful Improvements in Cream-Raising Appaio ratus, of which the following is a specification,

reference being had therein to the accompanying drawings.

Our invention relates to cream-raising apparatus, and is designed to facilitate the accui 5 rate final separation of the cream from the milk after the former has been raised from the latter; or, in other words, afterthe primary separation has been effected. i

The invention has particular reicrcnee to 2o that class of apparatus which is provided with transparent panes, and more particularly to apparatus and the subdivision of such class in which a single transparent pane is employed in contradistinction to two transparent panes 2 5 between which is a space which is usually occupied by water, the same being used as a refrigerative agent and conducting medium..

The object of the invention is to reduce the cost of manufacture and to simplify the cou- 3o struction, and to present a substantially unbroken lline or surface of the wall of the milkea'n in which the transparent pane is located, whereby liability to break the cream-line is avoided as the same comes in contact with the 5 5 transparent panel, and to provide an outlet in the can having no irregularity of contour above the lowest point of the can-bottom, whereby an unobstructed flow and a complete emptying of the can are secured.

Referring to the drawings, Figure l is a perspective of a combined Creamery and re f ri gera- -tor provided with our improvements. Fig. Z is a similar view of a Creamery embodying our improvements. Fig. 3 is a vertical section on i5 the line X of -Fig. 2. Fig. Lis a like section on an enlarged scale. Fig. 5 is a vertical section through the faucet, and Fig. 6 a horizontal section and end elevation of the `faucetsocket.

Serial No. 208,202.

(No model.)

Like letters of reference indicate like parts 5o in all the lignres of the drawings.

A represents any suitable casing, which may or may not, as preferred, be provided with a refrigerati ngchamber, B, for general purposes. rlhe casing A is provided with a lin- 55 ing or tank, C, which is completely contained within the casing, except at the .points D, where the inspection-panel l. andthe dischargefaucet lI of milk-can G are located. l'flcretofore doors have been provided for exposing 6o the tank or lining in which the sight-panel and discharge-faucet are arranged. By removing a portion of the fixed or permanent walls of the casing the lowercompartment need not be opened to gain access to these elements; 55 and hence the contents of the can may be withdrawn at any time without admitting the outer warm air into the lower compartment or refrigerator to the detriment of the articles stored therein.

As clearly shown in the drawings, the tank C is directly exposed at the openings D, and is provided with apertures E and F. The larger aperture,F,is covered by the sight-panel I, and the smaller aperture, E, communicates 75 with the faucet, as hereinafter described.

The socket lil (see Fig. 5) extends exteriorly below the longitudinally and transversely slanted bottom C of the can G, and is provided with a projection, Ff, (see Fig. 6,) hav- 8o ing an upper face, E, conforming to the bottom, to which upper face the bottom is secured by solder or other suitablemeans. This projection forms a half hood or step on the rear wall ofthe socket, so that when the fau- 8 5 cet Il is secured therein the lower surface of the bore of the discharge-tube of the faucet is below the plane ofthe bottom of the can at its lowest point, as clearly shown in Fig. 5, so that an unobstructed passage is provided for 9e the milk from the can and through the faucet, and the collection of milk, sediment, or other matter in the discharge-passage of the can is avoided.

The socket F (see Fig. 3) is provided with 95 au interiorly-projectiug annular ilange, F2, at its rear end, which is soldered directly to the outer surface of the Wall of the can, while in and cornes in contact with the panel there is equal depth from front to rear, so that when a A can is placed in the tank thc faucet H may be v 3o the transparent panel and that of the wall of l ment ofthe interior surface of the can to propanel so arranged that it does not restrict or .socket F to the can, the gland Fz might be secured thereto, and a socket screwed onto the preferable from the fact that the glass would.

Fig. ,Lsaid flange is discarded and its function performed by the wall of Arthe can itself. rlhis socket is also interior-ly screw-threaded to receive the gland or annular nut F3. A transparent disk, I, is, withsuitable packing o n one or both sides thereof, first inserted in the socket, andthe annular nut or gland is screwed to place against the packing and panel, so that only the thin interior annular iiange, F2, occurs between the inner surface of the can, whereby as the cream-line approaches no materially abrupt prominent disarrangcduce a breakage of the cream-line and a consequent intcrmingling of the cream and milk, whereby said cream line is rendered indistinet, and whereby uncertainty prevailsin regard to the proper time to close the faucet, in order to prevent the withdrawal of the cream with the milk.

The gland F1 is provided with apertures F, whereby a suitable wrench adapted to fit the same maybe employed for removing it for any purpose desired.

It will. be noticed that both sockets are of screwed into the socket E, provided for the same, and the said faucet being also provided with a jam-nut, H', it will readily be observed that a water-tight joint will be made between the outer surface of the socket, the inner surface ol" the lining or tank against which the socket is drawn, and between the said lining and the outer surface of the socket F, by reason ol' the flange on the gland, which, when the gland is secured into the socket, is drawn snugly against the outcr surface ol the lining. Especially will this be the case when any suitable packing, J, is providedl at one or both sides ofthe lining.

The parts being constructed as described, simplicity and cheapness of manufacture are apparent, as well as the advantages ol" having the transparent pane immediately in contact with the milk and cream within 'the can, and at the same time securing `the advantage of having a space between the tank and the front wall of' the can, in which the ref rigcrative agent may circulate, while by removing a portion of the outer casing itself an unobstructed view ol' the panelv and contents of the can is secured, and this through asingle transparent prevent a complete surrounding of the milkcan by the refrigerative agent.

It is apparent that instead ol' securing the gland; but this form of construction is not packing, and an exteriorl provided at its discharge end Y an interiorlyflanged socket, a transparent' i pane arranged against said flange, and agland j `for securing said pane in position, substantially as specified.

2. A milk-can having secured to the delivery end thereof', and in proximity vto the discharge-faucet thereof', an interiorly-fianged socket, in combination with a lining, a trans-` able packing, whereby said 'gland serves the `8o parent panel, with va flanged gland and suitdouble function of forming a water-tight joint at the rf `iel and. at thelining, snbstantia-ly as specified. .v l ,A u

3. A milk-can provided at its deliveryfend with two sockets rigidly secured thereto, one` of which is provided-with atransparent pane, in combination with an apertured tank and lining, a flanged gland, and a faucet havinga jam nut, whereby water tight joints areV formed at the transparent pane or panel :and f at the inner surface of the lining and sockets,

and a continuous space is providedfor'the re"y frigerative agent, substantially as specified.

4L. The combination, with the delivery end' of amilk-can, of an interiorIy-fianged and in teriorly-screw-threaded sockma' transparent pane arranged against the ange, suitable y-threaded gland, substantially as specified. l

5. The combination, with Athe discharge-y faucet ol" a milk-can, of a socket for receiving IOO said faucet providedlufithvav projection eX-.

tended beneath and secured to the the can, substantially as specified.

6. The combination of' the can G, having an ap rtnrc, u", or the transparent panel I, the socket F', the exteriorly-serew-threaded gland F, having the -liange F4, the lining 0,-having the aperture F, and suitable packing, J, substanti-all y as specified.

7. rlhe combination of the 'case A, having the openings D and provided with thedining C, having the openings E and- F, with the transparent pane I, socket F,4 and gland F3, and, with the socket E', having the-projection E2, faucet H, and jan1-nut H,substantially as specified.

In testimony whereof we affixl tures in presence of two witnesses. A
